More infused with a spirit than put together according to a set of rules, cottage-style interiors have a happy informality. Rooms are airy and intimate at the same time, with nooks and alcoves that offer both curl-up daydreaming spots and space-saving built-in storage—after all, who can relax if there's clutter all around? From colorful weathered paint to warm stained wood, finishes are touchable rather than hands-off and only get better with age. These spaces often get a dose of nostalgic charm from vintage-look fixtures and fittings, hardware, and woodwork details that seem to turn back the clock on today's high-stress, high-tech lifestyle. Most any place can use a helping of cottage coziness, as long as the goal is to create an inviting interior with a carefree, well-lived-in look. Here and on the following pages, we highlight some key features that you can borrow to give your own home that uplifting, easygoing feeling.
